%% 1) create axes and 2d plot
haxes = axes;
xvec1 = linspace(1,100,10);
yvec1 = linspace(1,100,10);
xvec2 = linspace(1,10,10);
yvec2 = linspace(0,10,10);
himg = imagesc(haxes, xvec1, yvec1, rand(10,10));
set(himg, 'XData', xvec2, 'YData', yvec2)
%% 2) manipulate plot using interactive zoom tool of axes
%% 3) set new axes lim
set(haxes, 'XLim', [xvec2(1),xvec2(end)], ...
'YLim', [yvec2(1),yvec2(end)]);
I expected that default zoom buttom goes to new axes limits after step-3, but, it doesn't.
Default zoom button makes plot image fit to axes limits in step-1.
How do I update default zoom parameters? XLim, YLim never works.
Thank you.

In order to understand this better, I would need the following information:
  1. Default axes limits seems to have changed after step-3, refer the attached fig for reference.
  2. What difficulties are you facing in achieving the attached results.

To manually update the view of MATLAB figure window with latest 'xlim' and 'ylim', use the 'zoom reset' MATLAB command as part of step-3. Follow the code snippet mentioned below for reference:
%% 1) create axes and 2d plot
haxes = axes;
xvec1 = linspace(1,100,10);
yvec1 = linspace(1,100,10);
xvec2 = linspace(1,10,10);
yvec2 = linspace(0,10,10);
himg = imagesc(haxes, xvec1, yvec1, rand(10,10));
set(himg, 'XData', xvec2, 'YData', yvec2)
%% 2) manipulate plot using interactive zoom tool of axes
%% 3) set new axes lim
set(haxes, 'XLim', [xvec2(1),xvec2(end)], ...
'YLim', [yvec2(1),yvec2(end)]);
zoom reset;
